1) Characterize heritability and other traits of rootworm larvae that exhibit Bt tolerance.
Newly emerged virgin male and female western corn rootworm adults from both Cry34/35Ab1-selected colonies and their control colony will be collected and isolated from each other by the cooperator. Reciprocal cross colonies will be created by combining at least 100 Cry34/35Ab1-selected males with 100 control females and vice versa for each from both Cry34/35Ab1-selected colonies. Eggs from these colonies will be collected and tested along with those of the parental Cry34/35Ab1-selected and control colonies in diet-toxicity and plant assays similar to those that we have published previously.
